Phenomenological Theory of Isotropic-Genesis Nematic Elastomers

Abstract

We consider the impact of the elastomer network on the structure and fluctuations in the isotropic-genesis nematic elastomer, via a phenomenological model that underscores the role of network compliance. The model contains a network-mediated nonlocal interaction as well as a new kind of random field, which reflects the memory of the nematic order present at cross-linking, and also encodes local anisotropy due to localized polymers. Thus, we predict a regime of short-ranged oscillatory spatial correlations (both thermal and glassy) in the nematic alignment trapped into the network.
